Is there an easy way to determine exactly the "fuzziness" of a datafile .... Dump the datafile header and look at the status. Fuzzy statuses are: 0x01 hotbackup in progress on file 0x04 online fuzzy - it was online and the db was open 0x10 media recovery fuzzy - file is in media recovery 0x40 absolutely fuzzy - fuzzyness from file scan ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Donahue, Adam Sent: Thursday, December 14, 2006 11:03 AM To: oracle-l@xxxxxxxxxxxxx Subject: Determining the "fuzziness" of a datafile Folks, Is there an easy way to determine exactly the "fuzziness" of a datafile that's been restored from an RMAN back up as part of a clone operation (meaning with a backup controlfile), without having to look at the backup catalog itself? That is, as far as I can tell, when a backup at time 0 is started and completes at time 100, the blocks of the files backed up in that period could reflect anything from 0 to 100 depending on when they were read. And of course we need to redo containing those changes. But v$datafile (and v$datafile_header), as well as v$database, don't give an indication of exactly how much redo is needed to bring the database back to a consistent state. Is there a way to say "What's your max (or min) SCN?" or is this a lower-level operation that would require tracing. I figure it must be somewhere - but I didn't see the SCN noted anywhere upon a cursory glance.
